The goal of this note is to understand and design CMOS active filters.
Topics covered includes: Active-RC Filters Fundamentals, Two integrators
Active-RC, and Mason Rule, Noise in Active-RC Filters, Example of FD Active-RC
Filters, OTA-C Filters and tuning techniques, Linearization Gm-C, Q-tuning
adaptive technique, Non-Linear Macromodeling, Current-Mode Filters, Active-R
Filters, Sinusoidal Oscillators: Quadrature and BP based, Higher-Order Filters:
Cascade and Follow the leader and an example, Higher-Order Filters: Leapfrog,
Switched-R and Based on VCO integrators, Switched-Capacitors.
